MMT

Question 0

Grade: trace

Answer 0

(T or 1)

No joint motion, gravity minimized position, muscle contraction palpable or observable

Question 1

Grade: zero

Answer 1

(0)

No observable or palpable muscle contraction

Question 2

Grade: trace+

Answer 2

(T+ or 1+)
Able to move through less than half the full ROM, in gravity minimized position and no manual resistance
-May need help to start

Question 3

Grade: poor-

Answer 3

(P- or 2-)
Able to move through more than half the full available ROM, in a gravity minimized position and no manual resistance
-still just observation

Question 4

Grade: poor

Answer 4

(P or 2)

Able to move through the full ROM, in a gravity minimized position and no manual resistance

Question 5

Grade: poor+

Answer 5

(P+ or 2+)

Able to move through less than half the full available ROM, against gravity and no manual resistance

Question 6

Alternative definition for P+

Answer 6

Able to move through full available ROM, in a gravity minimized position, able to accept manual resistance somewhere in the range of movement

Question 7

Grade: fair-

Answer 7

(F- or 3-)

Able to move through more than half the full ROM, against gravity and no manual resistance

Question 8

Grade: fair

Answer 8

Able to move through full available ROM, against gravity and no manual resistance

Question 9

Grade: fair+

Answer 9

(F+ or 3+)

Able to move through the full ROM, against gravity, able to accept minimal manual resistance

Question 10

Grade: good

Answer 10

(G or 4)

Able to move through the full ROM, against gravity and moderate manual resistance

Question 11

Grade: normal

Answer 11

(N or 5)

Able to move through the full ROM, against gravity and maximal manual resistance

Question 12

Special grades

Answer 12

Scapular muscles (isometric, can patient stabilize scapula or not?)

Fingers & toes (because weight of digits is minimal, does not matter if tested in gravity-lessened position or against gravity)

Weight bearing muscles (need full body weight for resistance-most examiners cant apply manually)

Facial muscles (cannot apply resistance, may be diff to palpate)

Question 13

Patient position and instructions

Answer 13

• stabilization
• apply resistance
• lever arm length
• grade it

Question 14

Therapist posture

Answer 14

correct biomechanics!!!
-engage abdominals, posterior pelvic tilt, keep close to patient, wide BOS

Support patients limb
-proximal and distal segments, May cradle in forearm

Question 15

Knowledge required to perform MMT

Answer 15

• normal ROM
• muscle innervation
• effects of fatigue

Question 16

Approaches to strength testing

Answer 16

Isotonic (testing of strength using a constant external resistance)
Isokinetic (resistance through a ROM at a constant velocity)
-expensive, not highly used
Isometric (muscle generates force against and immovable resistance)
-most common
